WO-96/37494, WO-98/25923), and preparations which comprise insecticidally active plant extracts, nematodes, fungi or viruses.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners and/or semicochemicals is also possible.

In addition, the compounds of the formula (I) according to the invention also have very good antimycotic activity. They have a very broad antimycotic activity spectrum in particular against dermatophytes and yeasts, molds and diphasic fungi (for example against Candida species such as Candida albicans, Candida glabrata) and Epidermophyton floccosum, Aspergillus species such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis and audouinii. The list of these fungi does by no means limit the mycotic spectrum which can be covered, but is only for illustration.

The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading, etc. It is furthermore possible to apply the active compounds by the ultra-low volume method, or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of the plants.

When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha. For seed dressing, the active compound application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. For the treatment of the soil, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 1 and 5000 g/ha.

The compositions used for protecting engineered materials generally comprise the active compounds in an amount of from 1 to 95%, preferably from 10 to 75%.

The use concentrations of the active compounds according to the invention depend on the type and the occurrence of the microorganisms to be controlled, and on the composition of the material to be protected. The optimal rate can be determined by test series. In general, the use concentrations are in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the material to be protected.

The activity and the activity spectrum of the active compounds to be used according to the invention in the protection of materials or of the compositions, concentrates or quite generally formulations which can be prepared therefrom can be increased by adding, if appropriate, further antimicrobially active compounds, fungicides, bactericides, herbicides, insecticides or other active compounds to widen the activity spectrum or to obtain particular effects, such as, for example, additional protection against insects. These mixtures may have a wider activity spectrum than the compounds according to the invention.

When used as insecticides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergists. Synergists are compounds which increase the activity of the active compounds, without it being necessary for the synergist added to be active itself.

When used as insecticides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with inhibitors which reduce the degradation of the active compound after use in the vicinity of the plant, on the surface of plant parts or in plant tissues.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

They are applied in a customary manner adapted to suit the use forms.

When used against hygiene pests and pests of stored products, the active compound has excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof, are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.

Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having new properties (“traits”) and which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be cultivars, varieties, bio- or genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

The transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful properties (“traits”) to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defense of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized are in particular increased defense of the plants against insects, arachnids, nematodes and slugs and snails by toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defense of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucoton® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulfonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned also include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars which have these genetic traits or genetic traits still to be developed, and which will be developed and/or marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula (I) or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.

The preparation and the use of the active compounds according to the invention is illustrated by the examples below.

PREPARATION EXAMPLES EXAMPLE 1

N-(4′-Bromo-1,1′-biphenyl-2-yl)-4-(difluoromethyl)-2-methyl-1,3-thiazole-5-carboxamide (0.3 g, 0.7 mmol) is initially charged in tetrahydrofuran (20 ml), and sodium hydride (60%, 34 mg, 0.85 mmol) is added. After 15 min at room temperature, acetyl chloride (50 μl, 0.7 mmol) is added, and the mixture is stirred at 50° C. for 5 h.

For work-up, the mixture is washed with saturated sodium bicarbonate solution and extracted with ethyl acetate, and the extract is dried with sodium sulfate and concentrated under reduced pressure.

This gives 0.31 g (95% of theory) of N-acetyl-N-(4′-bromo-1,1′-biphenyl-2-yl)-4-(difluoromethyl)-2-methyl-1,3-thiazole-5-carboxamide of logP (pH 2.3)=3.61.

EXAMPLE 2

N-(4′-Chloro-1,1 ′-biphenyl-2-yl)-4-(difluoromethyl)-2-methyl-1,3-thiazole-5-carboxamide (0.3 g, 0.8 mmol) is initially charged in tetrahydrofuran, and sodium hydride (60%, 23 mg, 1.0 mmol) is added. After 15 min at room temperature, methyl iodide (100 μl, 1.6 mmol) is added and the mixture is heated under reflux for 16 h.

For work-up, the mixture is washed with sodium bicarbonate solution and extracted with ethyl acetate, and the organic phase is dried over sodium sulfate, filtered and concentrated.

This gives 0.25 g (80% of theory) of N-(4′-chloro-1,1′-biphenyl-2-yl)-4-difluoromethyl)-N,2-dimethyl-1,3-thiazole-5-carboxamide of logP (pH 2.3)=3.34.

The compounds of the formula (I) listed in table 1 below are obtained analogously to examples 1 and 2 and in accordance with the statements in the general description of the process (A). TABLE 1 (I)

Preparation of Starting Materials of the Formula (II) EXAMPLE (II-1)

At a temperature between −10 and −20° C., a solution of 21.8 g (0.10 mol) of 2-methyl-4-(difluoromethyl)-1,3-thiazole-5-carbonyl chloride in 200 ml of tetrahydrofuran is added slowly to 23.2 g (0.09 mol) of 4′-bromo-1,1′-biphenyl-2-amine and 26.0 ml (0.19 mol) of triethylamine in 1.0 1 of tetrahydrofuran. The reaction solution is stirred at 0° C. for 2 h. For work-up, the mixture is concentrated and chromatographed on silica gel using cyclohexane/ethyl acetate.

This gives 27.8 g (70% of theory) of N-(4′-bromo-1,1′-biphenyl-2-yl)-2-methyl-4-(difluoromethyl)-1,3-thiazole-5-carboxamide of logP (pH 2.3)=3.34 and melting point 151° C.

EXAMPLE (II-2)

At a temperature between −10° C. and −20° C., a solution of 56.3 g (0.27 mol) of 2-methyl-4-(difluoromethyl)-1,3-thiazole-5-carbonyl chloride in 500 ml of tetrahydrofuran is added slowly to 65.1 g (0.32 mol) of 4′-bromo-1,1′-biphenyl-2-amine and 74.0 ml (0.53 mol) of triethylamine in 2.0 1 of tetrahydrofuran. The reaction solution is stirred at 0° C. for 2 h. For work-up, the mixture is concentrated and chromatographed on silica gel using cyclohexane/ethyl acetate.

This gives 43.88 g (44.5% of theory) of N-(4′-chloro-1,1′-biphenyl-2-yl)-2-methyl-4-(difluoromethyl)-1,3-thiazole-5-carboxamide of logP (pH 2.3)=3.26 and melting point 144° C.

The logP values given in the preparation examples and tables above are determined in accordance with EEC Directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) using a reversed-phase column (C 18). Temperature: 43° C.

The determination is carried out in the acidic range at pH 2.3 using the mobile phases 0.1% aqueous phosphoric acid and acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile.

Calibration is carried out using unbranched alkan-2-ones (having 3 to 16 carbon atoms) with known logP values (determination of the logP values by the retention times using linear interpolation between two successive alkanones).

The lambda max values were determined in the maxima of the chromatographic signals using the UV spectra from 200 nm to 400 nm.
